Comments

  • At the core of an Observation is a flexible key-value pair (or a structured collection of key-value pairs), where a "key" field defines the type of observation made, and the "value" field describes the value or outcome of the observation. The fact that the type of observation captured is defined in the data allow Observation to convey a broad range of observation data.

    - This may be a type of observational, measurement, experimental, or computational
      method specifying how to generate data (e.g. "manual counting", "bright field
      microscopy",). Or a Guideline or SOP specifying how to interpret data and/or
      encode the result of an  Observation (e.g. a Cancer Staging system such as that
      defined by the AJCC, or variant interpretation guideline such as that provided
      by the ACMG).

    comments:
    - The "focus", "subject", and "specimen" fields are useful when data creators
      want an Observation object to stand on its own, so it can point back to the
      entities it is about.  These fields are not needed when an Observation is embedded
      in a Specimen or other entity, where focus, subject, and specimen can be determined
      from context.

  id:
    name: id
    description: The 'logical' identifier of the entity within the system of record.  The
      simple value of this attribute stands for an identifier of this data object
      within the system, it can be used as a reference from other objects within the
      same system (i.e. primary and foreign keys), and it should be unique per type
      of object. The same data object copied to a different system will likely have
      a different "id" in the new system since "id" values are system specific and
      do not represent persistent business identifiers. Business identifiers are assigned
      outside the information system and are captured in the "identifier" field. The
      "id" field is more likely to be a serially or randomly generated value that
      is assigned to the data object as it is created in a system.
